Reversing combination AC-3,18.5 kW/400 V,AC/DC 20-33V 3-pole, size S2 screw connection electrical and mechanical interlock 2 S integrated reversing combination SIRIUS 3RA23 for switching motors including changing the direction of rotation. The 3RA23 reversing combination is a tested and factory-preassembled combination of two 3RT2 contactors of the same power, which are already fully wired and mechanically and electrically interlocked. They are climate-resistant, approved worldwide (e.g. IEC and UL/CSA) and IE3/IE4 ready. The 3RA23 reversing combinations are available with AC and DC operation in sizes S00 to S3. They are offered with screw and spring-loaded connection technology for mounting on a DIN rail or screw fastening. The accessories for the 3RT2 contactors are standardized for all sizes and can also be used for the contactor assemblies. The 3RA23 reversing assemblies replace the proven 3RA13 series. Simple, efficient, always up-to-date - the SIRIUS modular system.
